what you can do is u can first create object in jQuery and make a ajax call to server using AJAX and server side you will get tht object and you can simply transfer that object value to your model value!!
$.ajax({
type: "GET", //GET or POST or PUT or DELETE verb
url: ajaxUrl, // Location of the service
data: yourObject, //Data sent to server
contentType: "", // content type sent to server
dataType: "json", //Expected data format from server
processdata: true, //True or False
success: function (json) {//On Successful service call
var result = json.name;
$("#dvAjax").html(result);
},
error: ServiceFailed // When Service call fails
});
server side
using System.Web.Services;
[WebMethod()]
//[ScriptMethod()]
public static void SendMessage(CategoryModel yourModelObject )
{
}
